"Works good on our well water. We have to replace them around 3 months because they catch so much sediment."
— Lynn M. (5/5)
"I wanted better filtration than the 5 micron. So I added two stages before the normal 3 and did the 5 micron then the 1 micron and in the original 3 stages the first one is another 1 micron. Water is at 14 ppm and going down still."
— Anthony T. (5/5)
"Our city water is truly undrinkable !!!! These filters make it taste like high cost bottled water. Prices are unbeatable."
— John K. (5/5)
"Just put in a couple weeks back. Not sure if this is a good product or not yet. Maybe I will have better review in six months to a year after it has been put through its paces. Too early to tell I guess. Seems like a decent quality filter looking at it before install."
